Bradley Cooper is a pretty big name in his own right these days, but bringing Cooper together with Robert De Niro and Abbie Cornish on "Limitless" makes for one star-studded affair. Cooper, De Niro, Cornish, director Neil Burger and screenwriter Leslie Dixon recently sat down with a group of journalists in New York to discuss the film and some of their other projects.

On working with De Niro: When I saw Robert De Niro's face, all his characters flashed before my eyes. Then that cleared and I saw this man who is Robert De Niro. It's surreal and wonderful and amazing.
